Designed to work in parallel in multiple units, they are an optimal solution for pressurisation equipment.

Their system of suction and delivery flanges on different planes makes them easy to install and service, while providing easy access to the valve and sensor units.

The system of in-line flanges makes them very easy to install and service.

Their reliability is added to their ability to work under many different conditions, and they are remarkable for their compatibility, including an ESD variable speed control module for automating their operation according to criteria of energy savings and installation efficiency.

They are particularly recommended for pressurisation at constant pressure.
